The correct answers are: They can sue immediately; They will only get nominal damages if they were unable to perform the contract themselves; They can affirm the contract so that it remains in force.

The repudiation does not automatically bring the contract to an end but gives the innocent party a free choice either to treat it as terminated or to affirm it and allow it to continue.

If they elect to terminate the contract, it is deemed to be discharged immediately and they can therefore sue for damages forthwith.

Damages will only be nominal, however, if they would not have been able to perform the contract themselves (The Mihalis Angelis 1971).
